ArcGIS 10.0: Creating MultiPoint - No FID for the 2nd set of points in Label. Why?

I tried to write a "MultiPoint" point feature by using the "MultiPoint" Python script copied from the Help of ArcGIS 10.0-see the attached file for the Python script I used. It ran and I got 7 dots in the .mxd Map: every dot is FID=0 in the Leabel. I believe that there should have FID=1 for the second set of the last 4 dots/points - please see the attached file for details. Could you please help and point out where in the Python script causes this problem?

I mistakenly said the FID in Label which is OK. What I have in the Label now is "id" that has 0 for the FID=0 and FID=1. This is not what I want in the result. How can I program to set the value of the second "id" to 1? Please help and advise.Thanks,Scott Chang
